Clinical presentation and radiography are unreliable in the preoperative diagnosis of fish bone perforation of the GI tract. This limitation can be overcome with the use of CT, which is accurate in showing the offending fish bone. The accuracy of CT is limited by observer dependence. A high index of suspicion should always be maintained for the correct diagnosis to be made.

The results of our study show that for large liver abscesses more than 5 cm, SD provides better clinical outcomes than PD in terms of treatment success, number of secondary procedures, and hospital stay with comparable morbidity and mortality rates. SD should be considered as first-line treatment of large liver abscesses.

Retroperitoneal schwannomas are rare tumors that are difficult to diagnose preoperatively. Radiologic findings are usually nondiagnostic. The treatment of choice is complete surgical excision.

We report a facile, solution-phase route to large-scale fabrication and characterization of single crystalline Cu 2 O nanowires with controllable diameter, different morphologies, and high aspect ratios. The synthesis of Cu 2 O nanowires is achieved by the reduction of cupric acetate with o-anisidine, pyrrole, or 2,5-dimethoxyaniline under hydrothermal conditions. The electrical properties of individual Cu 2 O nanowires have been examined by I−V characteristics. The output properties of Cu 2 O/poly(2,5-dimethoxyaniline) core/shell nanowires show n-type characteristics and improved conductivity, while those of Cu 2 O nanowires are linear. The results from this study provide a low-cost, naturally abundant nanostructured material for use in electronic devices.

Pancreatic MCNs with OS have unique and distinct clinicopathological features. MCNs should be defined by the presence of OS, as it is the most reliable way of distinguishing MCNs from IPMN. Adoption of "looser" criteria will result in misclassification of some IPMNs as MCNs.

SPPNs should be considered in young women presenting with a large solid-cystic pancreatic mass. Aggressive en bloc resection should always be attempted including resection of concomitant metastases as patients demonstrate excellent long-term survival even in the presence of distant spread.
